NOVATEK-ELECTRO
RNPP-311M
MIN voltage monitoring;
MAX voltage monitoring;
correct phase sequence monitoring and phase coincidence control;
phase imbalance control
Control of voltage presence on each phase is being performed at any position of 4-8 switches.
On special request it is possible to arrange operative input voltage of 24V for the RNPP-311M (
is
recommended for using in the network lines with a high level of harmonic waves)
.
ATTENTION
- the source of operational supply is galvanically connected to zero network.

*In case of minimal voltage alarm situation (
Umin
fault) then tripping time delay of 12 seconds will be applied on the following
conditions:
a)
U
max
and
U
min
switches are set to the left position
;
b) At any other combination of switches of Umax and Umin, of relay will work with the
T
off
time preset by the user;
If within this 12 sec time interval it will happen some other type of voltage interruption (for example
U
max
fault), then the
RNPP-311M will trip the power load with minimal time: with the
T
off
time preset by the user or the left time of 12 sec interval.
**
In case of maximal voltage mode
–
0.3 seconds.
